A Calabash bug; no doubt about it now. You should get the error with or without the p:group wrapper as nothing is connected to the primary output port of SAVEME. If this is intentional and you really don't care about the result of SAVEME, simply add p:sink right after it:

<oh:save-output name="SAVEME" step-name="saveidentifyDifferentOldNewOfficeCodes">
  <p:with-option name="save" select="'true'"/>
  <p:with-option name="href" select="$hrefIdentifyDifferentOldNewOfficeCodes"/>
</oh:save-output>
<p:sink/>

Thank should fix it.

Good call Vojtech,, I added a name to the save-output step and the error message is related to that step. I hadn't noticed that I was thinking the step-name was the name I suppose.

E [Calabash XProc] ERR : Unbound primary output: [output result on SAVEME]

   <oh:save-output name="SAVEME" step-name="saveidentifyDifferentOldNewOfficeCodes">

I assume that "!1.29" is the oh:save-output step as the other steps in the sub-pipeline have explicit names. I don't know what the declaration of oh:save-output looks like, but if the step has a primary output port, then this output port is unconnected (no steps inside p:group are connected to it, and no steps outside of the p:group can connect it as it is out of scope). If you look at the connections between the steps in the subpipeline, there are actually two branches:

- PutCopyCitySpecificWikiDump -> identifyDifferentOldNewOfficeCodes -> oh:save-output
- PutCopyCitySpecificWikiDump -> GetCopyCitySpecificWikiDump

My guess is that Calabash gets it wrong and somehow thinks that oh:save-output is the last step of the subpipeline, in which case it creates an implicit output port to p:group and connects it to the primary output port of oh:save-output. That would explain why you don't get the error with p:group, but I think that is a bug in Calabash.
